i just did a fresh install of ubuntu 12.04 - 32 bit on my vps.
then i created a new user and added it into "sudo" group to allow sudo permission. then i tried to sudo to see whether it works or not. then i got "sudo: must be setuid root" warning. after googling for sometime i found out that /urs/bin/sudo file must be given chmod +s permission to make sudo work.
I am trying to get around a permission issue I am having. The only reasonable option (other than ACL) is to add the user that needs access to the system group of the user that has access. Yes, the user that has access was birthed as a system user.
I can't seem to get my USB devices to show up in the Removable Devices list. I remembered having some similar issue with VirtualBox long ago and I added my user account to the VirtualBox user group or something similar to fix the issue.
I've set up a SFTP server using OpenSSH. After following a guide online, I set up a group called sftponly and added a user to this group. I used the Match group switch in the sshd_config file to match the group so that user's in that group could only connect for SFTP sessions. I set up the chroot to point to "/home/%u".
I have added the user "test" in myuser group [usermod -a -G test myuser]. But if try to execute or try to cd to datadir as "test" user gives the Permission denied error. datadir is having the following privilege [770 the user "test" is belongs to myuser group still it gives the Permission denied error].
